TRUCK FOR CARS, 86C.

SPECIFICATION forming part of Letters Patent No. 560,258, dated May 19,1896. Application filed February 15, 18 96 Serial No. 579,392. (Nomodel.)

To all whom it may concern:

Be it known that 1, JOHN TV. CLOUD, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Trucks for Cars or otherVehicles, of which the following is a specification.

My invention relates to the construction of trucks for vehicles, andmore particularly to those made of pressed or rolled steel plates.

Heretofore in the construction of steel cartrucks it has beencustomaryto cut away the side plates of the truck over the journal-boxesto form a cavity for the reception of the springs and then to strengthenthe truck side thus weakened by being cut away by securing to it a bentangle or T iron guide-piece or pedestal shaped to surround the cavity oropening thus formed.

My invention consists in forming the truck side with only a smallcut-away portion above the journal-box just sufficient to give thenecessary clearance for the play of the springs and in then mounting thesprings on either side of the truck side plate, by which means thestrength of the truck side plate is preserved, it not being injuriouslycut away, and I thus obviate the necessity for using the eX- pensivebent angle or T iron guide heretofore employed to strengthen the truckside plate.

My invention also consists in the novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described and more particularly specified in the claims.

In the drawings, Figure 1 is a partial vertical section taken in partcentrally through one of the journal-boxes and in part centrally throughthe truck-bolster. Fig. 2 is a horizontal section taken on line 2 3 ofFig. 4:. Fig. 3 is a View similar to Fig. 2, showing a slightlymodifiedconstruction. Fig. 4 is a plan View of a portion of the truck; Fig. 5, aside elevation, partly in section. Fig. 6 is a detail horizontal sectionshowing the shoes for the angle-iron guides, and Fig. 8 is a detailvertical sectional view of the same; and Figs. 7 and 9 are views similarto Figs. 6 and 8, respectively, showing the use of single instead ofdouble shoes.

In the drawings, A represents the wheels of a car-truck, A the axles, Athe journals, and A the journal-boxes, these parts being of any ordinaryor suitable construction.

a rectangular blank of steel plate without an y material waste by simplyclipping off its corners, as shown at b, and turning flanges I) at themiddle portion of the plate at is upper and lower edges, as is clearlyshown in Figs. 5 and 4. To give greater flexibility laterally, theflanges b taper out at the two ends of the side plate adjacent to the journal-b0Xes,where the side plate is left at its full depth or width, aswill be readily seen and understood from Figs. 5 and 4.

B B are the cavities cut out of the side plate to receive thejournal-boxes, these cavities or cut-away portions being comparativelysmall and just enough to receive the journal'- box and give thenecessary clearance-space B between the j ournal-box and the side platefor the play of the springs. By this construction I leave asufficientwidth or portion B of the side plate uncut away above the journalbox to afford the necessary strength for the side plate at thispart, so that I am enabled to dispense with the customary bent angle orT iron guides heretofore employed for surrounding and strengthening theside plate at this cut-away part.

The springs O O, which are usually and preferably four in number, Iplace 011 either side of the side plate B, the side plate thus extendingbetween the springs. The angleiron guides F F, I preferably form inseparate pieces, as shown in the drawings, one on each vside of thejournal-box, the same being securely riveted to the truck side B, and anangle or T iron piece or guide F, having a wider horizontal flange fthan the correspon ding flange f of the upright guides F to form abearing for the top of the springs G, extends across horizontallybetween the guides F F. This spring bearing-plate F is securely rivetedto the truck side plate B and is provided with lugs or projections f fto fit inside the springs to hold them in place. These lugs orprojections are preferably stamped or pressed in the plate F. Seats 7:.7L are formed on the lower bearing-piece II for the springs, which formsthe top of the journal-box.

Preferably a certain amount of play (indicated at h) is left between thevertical guides 71. on the journal box and the angle -iron guides F F onthe truck side B. This is clearly indicated in Figs. 4 and 2. Thispermits a certain endwise play of the axle and its journal-box, andprovision for the same play is also allowed between the springs and theside plate B, which fits between the springs, the springs being slightlyseparated for this purpose, as indicated in Fig. 1, so that the sideplate B will not strike the springs when the springs move with the axleand its journalbox in the endwise play of the axle.

In the modification shown in Fig. 3 no provision for play of the axleendwise is made, as the guides 7&2 71/ on the journal-box fit the guidesF F on the side plate B closely. This construction prevents the crossstrain on the springs, causedby the endwise play of the axle, and whichcross strain on the springs is what is usually relied upon to bring theaxle back to its central position, as shown in the drawings in Figs. 1and 4.

in Figs. 7 and 9.

The. shoe-K is preferably furnished with flanges 70 7t, embracing theangle-iron guides 1 F F, or other suitable means for holding it in placelaterally, and it is held inplace vertieallyby abutting against suitableupper and lowerstops, as 7a 79, or other suitable means,

'the lowerstop k being in this case the cross-bar atthe bottom of thebox. As illustrated in Fig.

S), the shoe K is held in place against movem ent vertically in bothdirections by the crossbar the shoe having a lug or part 713 fittingbelow the crossbar The shoe K it will thus be seen may be easily removedand renewed with a new one when worn without known construction.

taking the weight off the box by simply driving or slipping it downwardor upward from below, the hinged cross-bar k being of course swung openor removed. The shoe K,in cases where two shoes are employed, as shownin Figs. 6 and 8, is secured to the journal box, this being done by anysuitable means-as, for example, by turning lips 75 on the upper andlower edges of the shoe.

The bolster D may be of any suitable or I prefer, however, to form it oftwo ehannel-bars spread apart at the middle by suitable struts orspacing-pieces D D and having their flanges (Z notched or serrated attheir meeting ends, as shown at cl,

and held together by tie-pieces or other suitable means.

The truck side plates B are each provided with a flanged opening B attheir middle to receive the end of the bolster D, the opening beingformed by forming a small opening or slit and turning the edge of theplate surrounding the same outward into a flange b,

which flange is securely riveted to the bolster, as shown in Figs. 1 and4:. To further strengthen the connections thus formed between thebolster and the truck side, I rivet braee-pads or an gle-pieees M bothto the truck side and to the bolster.

The bolster D is provided at its middle with a lower center plateN andan upper center plate N, the lower beingsecured by rivets or otherwiseto the bolster. The upper center plate N is provided with an upturnedflange 01, surrounding the holefor the center pin to prevent the edge ofthe cen terplate from cutting or wearing the ccnterpin and to give abetter bearing against the pin, and the bolster D is provided with asimilar downturned flange n, surrounding the pin-hole for the samepurpose.

The truck side 13, aswill be seen from the drawings, is furnished withcomparatively narrow flanges Z) Z) at its upper and lower edges for thepurpose of making this truck side plate flexible laterally. This elasticflexibility laterally in the truck side is of great i1nportance insoftening the shocks and increasing the durability of the truckconstruction as a whole, as well as tending to relieve thejournal-bearin gs from excessive endwise pressure and wear. To increasethis lateral flexibility of the truck side, I sometimes make the flangesb b narrower than indicated in the drawings, as indicated in the dottedlines b Z) of the drawings, or, if preferred, these flanges 12 b may beentirely omitted at the top and bottom of the truck side plate.

I claim- 1. In a car-truck, the combination with the journal-box of apressed or rolled steel side plate extending across the journal-boxabout central thereto, and having a small cut-away part or opening abovethe journal-box to give sufficient clearance for the play of thesprings, and springs located over the journal-box on each side of saidside plate so that the weight will be distributed uniformly on thejournal, substantially as specified.

2. In a truck,the combination with the journal-box and springs locatedover the journalbox on each side of the truck side plate, of a truckside plate extending between said springs and having a cut-away partabove the journal-box suflicient to give clearance for the play of thesprings, substantially as specified.

3. In a truek,the combination with the 3' ournal-box and springs restingthereon, of a side plate extending between the springs centrally overthe journal-box and having a sufficient clearance between its lower edgeand the journal-box for the play of the springs, and top bearing-platesfor said springs secured to said side plate at each side thereof nearits upper edge, substantially as specified.

4. In a truck, the combination with the journal-box and springs restingthereon, of a side plate extending between the springs centrally overthe journal-box and having a sufficient clearance between its lower edgeand the j ournal-box for the play of the springs, and top bearing-platesfor said springs secured to said side plate at each side thereof nearits upper edge, and angle-iron guides formed in separate pieces andattached to said side plate at each side of the journal-box,substantially as specified.
